Why Does My Digital Boring Head Display Read Accu?

Accu is the message that is displayed when the battery needs to be changed.

This message does not mean there is an error or accuracy malfunction with the boring head. The head should still continue to function for a few more adjustments. If this message appears on the EWE heads, the wireless connectivity to the App and history functions are deactivated until the battery is replaced. Please remove the old battery and wait 2 minutes before placing the new one. This will ensure a complete internal reset.
